SPECIFICATION forming part of Letters Patent No. 754,178, dated March 8,1,904.

' Application iiled July 25, 1902. Serial No. 117,030. (No model.)

To all whom, it Tie/ty concern.:

Be it known that I, THEODORE T. WEBER, of Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Oarbureters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in ap- .paratus for carbureting airfor use as fuel or `for illuminating purposes; and the object of theinvention is to provide a simple, reliable, and effective carbureter inwhich the air is passed through saturated parts to which the liquidhydrocarbon is gradually and automatically fed in the proper quantitiesto charge the air with the proper proportion of vapor.

To this end the invention' consists ofthe new and novel arrangement andcombination of parts, as will be hereinafter described, andparticularlypointed out in the appended claims.

In the drawings, Figure 1 is a central vertical section of the completecarbureter. Fig. 2 is an enlarged vertical section of thecarbureting-chamber. Fig. 3 is a horizontal section taken on the line e2, Fig. 2. Fig. 4 is vrtical longitudinal section of the drip- Referringto the drawings in detail, like numerals of reference refer to likeparts in the several figures.

The reference-numeral 1 designates the airtank, having an inlet-pipe 2leading to any suitable pump or air-compressing device, (not shown,) and3 designates the hydrocarbon-supply chamber, which may be constructed inany suitable form.

In the accompanying drawings I have shown a superposed gas-receiver 4,in which the carbureted air is stored; but this receiver -need notnecessarily be-located as shown and is simply illustrated to completethe system.

If desired, the said gas-receiver may be located in any other suitableplace and Vin lsome instances can be dispensed with entirely and thecarbureted air led to the place of consumption directly. Y

Connecting the compressed-air tank with the hydrocarbon-supply chamber,near the upper end thereof, is an air-supply pipe 6, having locatedtherein `a suitable valve 7 by means of which the supply of air to thehydrocarbon-supply chamber is regulated or entirely shut off.

The hydrocarbon contained in the supplychamber 3 does not completelyiill said chamber, and above the iiuid is an air-space 8, supplied withair from the compressed-air tank 1 through the supply-pipe 6.

9 designates the carbureter proper, consisting of a chamber 10, hereshown as being cylyindrical, but which may be of any other formation andhaving its ends closed, as at 11. In this chamber are located horizontaldiaphragms 12, each comprising two Wire screens 13, having a sheet ofasbestos, wool, or other absorbent material 14 interposed therebetween.In the drawings four diaphragms are shown in the chamber 10; but, ifdesired, only one or any other number of diaphragms may be used. Thesaid carbureting-chamber is located in the hydrocarbon-supply chamber;but this need not necessarily be so. An airsupply pipe lenters thecarbureting-chamber from the bottom and is led out through thehydrocarbon-supply chamber and connects with the air-supply pipe 6, but,if desired, may be connected tothe compressed-air tank directly; A valve16 is located in the airsupply pipe 15 and is adapted to be actuated toregulate or shut off the supply of air to the carbureting-chamber.

The upper Wall of the carbureting-chamber 10 is provided with adrip-opening 17, over ply chamber and is connected at its lower end by ashort horizontal pipe 25, entering said supply-chamber below the surfaceof the fluid contained therein, and at its upper end the said pipe 24 isconnected to a horizontal pipe 26, which enters the said supply chamberabove the surface of the Huid contained therein and terminates in thedrip-head 20 directly over the drip-opening 17 in the upper end of thecarbureting-chamber 10. Hand-valves 27, preferably of the needle-pointtype, are provided at the points of connection of the vertical pipe 24with the horizontal pipes 25 26 to control the quantity of liquidsupplied to the carbureting-chamber 10.

28 is the carbureted-air or gas-outlet pipe` secured to the upper end ofthe-carburetingchamber 10, and this pipe is led to the gas-receiver 4:,which has an outlet-pipe 29 secured in its upper end leading to thepoints, of consumption.

The operation of the apparatus is as follows: The hydrocarbon-supplychamber 3 is partly filled with gasolene or other mineral oil, leavingan air-space between the head of the chamber and the surface of thefiuid; The compressed air is admitted to the hydrocarbon-supply chamberand forces the fiuid contained therein in proper quantities, regulatedby the valves 27 through the Huid-feed pipe 19 to the drip-head 20,where it passes out through the gradually-restricted or taperingapertures 21, which apertures feed lthe fluid onto the tapering pins 22,projecting therethrough. The apertures 21 and the pins 22, by reason ofthe formation just described, feed the fluid into thecarbureting-chamber in a continuous and exceedingly fine stream when thevalves 27 in the feed-pipe 19 are properly adjusted. The iiuid as itleaves the tapering pins 22 drips onto the uppermost of the series ofdiaphragms and saturates the interposed absorbent filling. After thelatter is completely saturated with the hydrocarbon it allows the excessfiuid to drip onto the absorbent sheet of the next diaphragm,which inturn will pass off all surplus drippings onto the absorbent sheet of thenext lower diaphragm, this being continued throughout the series, andthe quantity of fluid fed to the carbureting-chamber can be regulated tomeet the absorbing qualities of the absorbent sheets and -also tothe-number of such sheets used.

When the absorbent diaphragms are saturated, compressed air is suppliedthrough the pipe 15 and passes up through the hydrocarbon-saturateddiaphragms and finally out through the outlet-pipe 28 into thegas-receiver. In passing through the said diacarbureting-chamber, meansfor regulating the supply of the said fluid to said carbureting-chamber,and a pipe leading from the said air-tank to the Huid-supply chamberabove the surface of the iuid contained therein, whereby the said fluidis forcibly caused to enter the carbureting-chamber.

2. In a carbureter, the combination of a fluid-supply chamber, acarbureting-chamber within said fluid-supply chamber, an air-supply pipeleading to the supply-chamber above the iuid contained therein, aHuid-supply pipe connecting the supply-chamber below the surface of thefiuid with the upper end of the carbureting-chamber, and an air-supplypipe en- 'tering` at the lower end of said carburetingchamber.

3. In a carbureter, the combination' of a fluid-supply chamber, acarbureting-chamber having its upper end in a plane above the surface ofthe fiuid contained in said supply-chamber, a fluid-supply pipeconnecting the said supply-chamber below the surface of thefiuid withthe carbureting-chamber above the surface of the fluid, an air-supplypipe connected to the bottom of said carbureting-chamber, and anair-supply pipe connected to the upper part of the fluid-supply chamber.

4. A carbureter comprisinga chamber having an air-inlet at its lowerend, a gas-outlet and a drip-opening at its upper end, a hood above saiddrip-opening, a diaphragm containing absorbent material and permittingthe passage of air therethrough, a iuid-supply pipe entering said hoodand terminating in a drip-head located above said drip-opening, saiddrip-head having tapering perforations, and drip-pins extending throughsaid perforations.

5. A carbureter comprising a chamber having an air-inlet at its lowerend, a gas-outlet 1 and a drip-opening at its upper end, a hood abovesaid drip-opening, a plurality of diaphragms located in said chamber andconsisting of two screens and absorbent material between said screens, afiuid-supply pipe entering said hood and terminating in a drip-headlocated above said drip-opening, said driphead having taperingperforations, and drippins extending through said perforations.
